STONE-PICKER Application illed July 20, 1916.

To all whom it may concern.'

Be it known that I, JOSEPH J. VOGEL, a citizen. ofv the United States,residing at Springeld, in the county of Brown and State of. Minnesota,have invented a-new and useful Stone-Picker, of which the following isspecification.

My invention relates to devices for gathering and eiticient device ofsaid kind, be a riding machine adapted to be drawn by horses or otheranimals or motive power of any kind.

i wheels 3 which. by

In the accompanying drawings, Figure 1 is a top or plan view of myimproved stone picking machine arranged for operation by draft animals.Fig. 2 is a sectional front elevation 0n the line hea .F ig. 3 With thefork 10-1Oa .interseeted at the line ZJ and the lever 3.1 and some otherparts omitted. Fig. 3 is a side elevation of the machine shown in Fig.1, with one of the supporting wheels removed. Referring to the drawingsby .reference numerals, l designates the main frame, which is supportedby an axle 2 and tWO dogs (not shown) are so connected that they willrotate the axle when the machine is moving forward. To enable themachine to be drawn by draft animals it is'provided with poles 4, 4,neck yokes 15, 5, Whiiiie-trees 6, swingle-trees 7 and an evener bar 8;to the latter bar is attached by a link the draft bar-"10, having a slot11 on a bolt 12 in a bracket 13, as Vbest shown in F ig. 3. Said draftbar has its rear end bifurcated into two arms 10a, whichv arepivotally'securedI at 14 to the front corner ar'ins 'of a frame 16. Thelatter frame has pivoted' by an "17., in brackets 18 of the mam frame 1.In

said frame 16 is mounted an inclined endess` elevator or conveyer 19,forward of which the frame has a toothed shovel 20 (see Figs.` 2 and 3)by which to gather and guide the stones upwardly, rearwardly and to saidconveyor. The conveyer 19 delivers the stones into a transversely arraned inolined endless conveyer 21, which elivers the stone into a wagon(not shown) driven alongside the machine. The means whichdrive theconveyers and gather the stone`- in frontof the shovel, and otherfeatures,

will now be described.

say from two inches to eight inches in diameter',

,of the shovel by rearwardly converging rakes i12, which are pivoted at23 (see Fig. 1) and .may be raised and lowered by a hand .lever 2 L,.rock shaft 25, rocker arms 26, and links 2, a notched sector 28 and adog 29 on the evcr serving to hold the rake at the desired elevationeither in or abo.e the ground.

In sinilar manner the shovel is held at the desired elevation above ordepth in the ground by a link 30,' lever 31, sector 32 and (100' 33.ll/r u1 `zed between the arms 15 is a short endless convey/ercomposedof endless chains 34 carry ing toothed blades 35 which act as rakes tomove the gathered stones rearwardly over the shovel or scoop 20.

.he 12min axle 2 carries a fixed clutch member 36 (see Fig. l) withwhich meshes a slidabie clutch member 3T controlled by a shifter 38,link 39 and hand `lever l10, and lever ker ping pegs 41, a spring 12serving to throw the slidable clutch' member nor mally into .mesh withits mate.

The ell teh member 37 is fixed to a sprocket 43 which by a chain 14drives a sprocket 45 and a shaft 46 fixed therein and journaled acr )ssthe main frame.' On said shaft is fixed a gear wheel 48 fixed on thelower shaft 49 if the conveyer 21, which is thus operated.

Fixed cn the shaft 46 is also a sprocket 5.0 (see F. g. 1) which by achain 51 rotates a double sprocket 52 mountedl on a short shaft 53 (seeFig. 1) arranged in line, with the conveyer shaft 17, of which it maySaid double sprocket 52 drives an endless chain 54, and by it asprocket55 and the conveyor shaft 56 of conveyer 54-35 Fixed on the shaft 56 isagear 57 meshing with algear 58 ixed on the conveyer shaftv 59 which isthus rotated in the proper direction as best shown' in Fig..3.

On a post is mounted a seat 61 for the driver to o( cupy.

In furthn" explanation of the operation of the machine, it will l."understood by looking at ig. 3, that the bar 10, pivot 12, link 30,levir 31, sector 32 and dog 33 decide the depth o5 the shovel in theground or its elevation at ove the ground, and also bear a. portion ofthe pulling strain on the bar 10; the rest of V:he strain is borneby thepivot stones rearwardly over the shovel, a pair ofA 'ready beendescribed.
